NIELS K; NIELSEN, OF WIGHITA, KANSAS GARAGE-DOOR-OPEITINQ DEVIGEApplication filed April 19,

T he invention relates to an improved mechanism for openin and closingthe doors of a garage by a com inationof associated cleinents operablethe movements of the In the :eL-SUSLl practise, the driver of theautomobile goes to -the garage and opens the garage doors, then he backsout of the garage, next climbs onto-i the automobile and closes thedoor-s;- againhe gets into the automobile and drives away. Upon hisreturn, he gets out of the automobile and opens the garage doors, climbsback into the automobile and drives ,into theqgarzage then climbs outand J5 closes the doors ashe leaves the garage' By -Fr16a11l0f myinvention he opens the doors to goin, the automobile while backing outcloses the doors-,--and-on its return opens the doors and the driversimply closes the doors I '20 .assshe ileavesfithe garage. Thisprocedure is effected hyiemployiii'glairack with elements associatedtherewith operating through rod and bracket means attached to the doorsand driven by means carried upon the front axle 5 of the automobile. Themeans and procedure will be more fully understood by referring to thedrawings, in which Fig. 1 shows a fragmentary plan view of the garagewith its doors and the mechanism of the invention associated therewith.Fig. 2 is similar to Fig. 1, the doors being shown in their openedrelationship. Fig. 3 is a front elevation of Fig. 1. Fig. 4 is a frontelevation of Fig. 2. Fig. 5 is an enlarged detailed side 5 view of thetrip mechanism, seen in Figs. 1 and 2.

At 10' isseen .a track. element secured by brackets at 10* and l0 to thedriveway forward of thegarage and being centrally positioned between thedoor j ai nbswithout the This track: is-oi the type used for slidingdoors on b'ar-ns' and the like. A. housing ll is closed at each .end .asat 1 2 VVi-thin the housing 151 -is an element= 13 which 35 is mountedaupon paired wheels M operable upon thetraclr. 1.0.

The;pipe-15 spans between theelement 13-seenin Fig. 5.120 theelementlSfiwhieh-is similar tothe. element '13 but arranged within thetrack 10 at a distance towards the; garage. uupon the base of :theelement 13 rigidly .aflixed .a plate 27 which isprovided with twoholes,.- one on either side thereof into which engage the rods 28 and 29as seenin ,Fig. 9. The element 13 .is mounted upon the .paired wheels:30 and'3l which-travel in the track 10 in keeping with movementsofthewheels 14. Upon either garage door is attached a bracket such as seen at31 as applied to the exterior of the door 32 at the base thereof andnear the door jamb. The door 33 has a similar assembly for the rod 29.The rods 28 and 29 engaging their proper bracket 31 by means of a hookedend passing the hole 30 of the bracket.

At 34 is shown the front axle of the automobile to which a U-shapedmember 35 is bolted by the hook bolts 36 and 37 and in this member 35 isa rod 38 pivotally mounted upon the pin 39. The rod 38 is bent as seenin Fig. 13. The left hand end fits within a U-shaped guide 40, alsorigidly attached to the axle 34 by means of two bolts 41 and 42. An eye43 is formed on the rod 38 in which is fastened a cord or cable 44,which leads to any convenient position accessible .to the operator ofthe automobile and whereby the operator can pull upon the cord 44 sothat the rod 38 will swing upwardly in the direction of the arrow 45. Inthis raised position the rod 38 will not strike or catch upon highpoints in the road during road travel of the automobile.

Upon the return of the automobile to the garage, the doors being closedas in Fig. 1, the

iember 16 is positioned in a vertical position at the forward end of thetrack 10. The driver of the car loosens the cable 44 which allows therod 38 to drop down to the position seen in Fig. '13 or so that it willstrike the upper end of the member 16; then as the automobile movestowards the garage, the assembly 16 1315-13 moves with it being forcedby the rod 38 This movement causes the rods 28 and 29 to move from theposition seen in Fig. 1 to the position seen in Fig. 2 which operates topush against the brackets 31 of the doors 32 and 33 or so that theystand 0 en as in Fig. 2. By this time the part 13 as moved to andagainst the bracket 10. The spring tension 21 is sufficient up to thispoint to hold the part 16 in engagement with the rod 38 but now the part16 moves to the position 16 and the member 38 passes over the top of themember 16 and the automobile moves on into the garage. The driver stepsout'of the automobile, next closes the doors 32 and 33. When he nextopens the doors to remove the automobile, the mechanism stands as seenin Fig. 2; now the procedure is reversed, therod 38 now strikes themember 16 and as the automobile backs out of the garage, the pipe 15moves in its track 10 till the part 13-comes to the end bracket 10 whenthe spring 20 stretches to allow the member 16 to take the dottedposition'16 and the rod 38 passes over the top of the bar 16 and in thisposition the doors 32 and 33 are closed again as in Fig 1.

Such modifications may be employed as lie within the scope of theappended claims. Having fully described my invention, what I now claimas new and desire to secure by Letters Patent is:

1. In a device for opening and closing ga rage doors adapted to beactuated by means of a moving automobile; a stationary track attached tothe ground position forwardly extending from the garage; a movableelement for said track having wheels carrying elements at either end ofa pipe member; one of said elements carrying a spring controlled strikerpivotally attached thereto, the other element having a pair of rodsflexibly connecting thereto and brackets upon the garage doors flexiblyconnecting to said rods.

In a device as described in claim 1; and a rod supported from anautomobile axle adapted to strike the striker and move the carriageelement for opening or closing said doors as desired.

3. In a device of the class described; a track afiixed to the groundlevel, by securing means at either end thereof; a pipe on a movablecarriage within the track; a striker at one end of the pipe andflexibly'connecting rods at the other end of said pipe.

4. In a device of the class described, a track, a housing, an elementwithin the housing rigid thereto, wheels supporting said element fortrack travel and a striker hingedly attached to the housing and springmeans for supporting said striker in operative positions as desired anda pipe connecting said element to a second element similarly wheelsupported at a distance therefrom in said track; and rod means flexiblyconnected to the second element.

In testimony whereof I affix my signature.
